- ATTOR Patented June 29, 1937 UNITED STATES PATENT OFFICE COIN TESTING DEVICE Theodore Bibicos, Cleveland, Ohio Application March 12, 1936, Serial No. 68,472

, 2 Claims. (01. 194-403) This invention relates to fraud preventives for slot machines or the like, and in some respects is an improvement on the machines shown in the patents to Poulas Nos. 1,919,478; 1,977,326,

and 1,988,664.

The object of the present invention is to provide various improved devices for testing coins and ejecting slugs, but the claims of the present application will be confined to a so-called weight tester, which will separate and eject light weight slugs. The apparatus also includes size and material testers, which may be made the subject of separate applications.

In the accompanying drawing:-

Fig. 1 is a front elevation of the invention, partly in section, showing the coin passages and testers.

Fig. 2 is a longitudinal section on line 2-2 oi. Fig. 1 showing particularly the ejector for small 0 SlllgS.

Fig. 3 is a longitudinal section on line 3-3 of Fig. 1 showing the means by which a large slug is ejected.

Fig. 4 is a sectional view similar to Fig. 1 showing the operations by which a coin or a slug is directed through its proper channels.

Fig. 5 is an enlarged fragmentary elevation of a spring operated lever or pivoted beam.

Fig. 6 is an enlarged fragmentary elevation of a spring operated pivoted gate and release lever.

Fig. 7 is a perspectiveof the lever shown in Fig. 6.

Referring to the drawing, a casing III having a coin receiving slot I I in its top surface substantially as shown in Figs. 1 and 2, has mounted within said casing and under the slot II an angular coin passage member I2 secured to the inner casing wall I3 by screws I4, said member having a curved edge wall I5 directly beneath the slot II in the casing I0 and an offset ear I2a projecting from said member.

A second elongated coin chute I6 adjacent to said member I2, is also attached to the inner 5 wall I3 of said casing I0 by screws I'I, this elongated vertical coin chute or channel I6 terminating in a triangular bouncing block IIia at its lower end. A magnet I8 is secured to the elongated coin chute I6 by screws Ila, the legs I8a 50 of the magnet extending directly beside a triangular opening between the chute I6 and a channel I9.

The shield or bridging channel I9, with its lower edge 20 having a curved contour, is

55 mounted on the inner wall I3 of the casing I0 above the lower end of the coin chute I6 and secured by screws 2I. A projecting leg I9a of the shield rests against the triangular block Isa of the coin chute I6, the upper inner contour 23 of the said bridging channel I9 having substantially the same curve as the outer curved contour of the lower edge 20 of. the bridging channel I9. An adjustment screw 22 is mounted vertically through the wall of the bridging channel I9 as shown in Figs. 1 and 4.

A slotted lower vertical chute 24, flanged as at 25 and 26 is secured to the inner casing wall I3 by screws 2! and 21a adjacent to and below the outlet from the bridging channel I9.

A shield or" plate 28 is mounted over the slotted channel 24 and is secured also by the screw 21 and a screw 29 and has an incurved convex portion 39 directly below the lower curved edge 20 of the bridging channel I9. An angular piv-= oted gate or arm 3| is mounted on a pivot pin 32 in the wall I3 above and slightly to one side of the outlet from the bridging channel I9, a fiat coil spring 33 being attached at one end to the pivot pin 32 and coiled around said pin within the slotted aperture 34, the opposed end 3311 of the coil spring 33 being bent around the angular pivot arm 3| as shown in Figs. 1 and 5, to cause the said arm to return to its normal position after each pivoting action. The top portion 35 has a balancing arm 36 projecting therefrom.

A pivoted beam 37 is mounted on a pin 38 in the wall I3, and has a fiat coil spring 39 attached to and coiled around the said pivot pin 38 within the slot or groove 40, the action being such that the spring tends to hold the beam in substantially the position shown in Fig. 1. A stop 4I for the beam 31 with an adjustment screw 42 is secured to the wall I3 by a screw 653.

A release gate 44 is mounted on a pin 45 in the inner wall I3, adjacent to the slotted channel 24 and opposite to and slightly above the beam 31. v

A coin compartment 46 and a slug compartment 4'! are separated by a partition 48 in the lower end of the casing II].

A cover 49 is superimposed over the mechanism as shown in Fig. 1 and secured to the raised side ledges 50 by screws 5|.

In operation, a small slug A being inserted in the slot II, passes through the angular coin passage I2 and as it leaves said passage it strikes a set screw 52 set in the inner wall I3 of the casing II] and thereby the small slug A is diverted from its course and falls forward striking the ofiset ear Ma and is ejected outwardly as shown in Fig. 2 and falls into the slug compartment 41. The diameter of the small slug A" being less than the distance between the recessed finger I2b oi the passage l2 and the recessed projection lib of the elongated chute l6, allows the small slug "A" to fall forward as it is tipped off balance in striking the screw 52.

A large slug B being inserted in the slot ll, passes through the angular coin passage l2, and follows the sloping track formed by the recessed finger 12b of the passage l2 and the recessed projection 16b of the elongated chute IS, the set screw 52 failing to tip the large slug 3" forward due to the said slug being held in an upright position within the track by the forward edges of the recessed finger l2b of the passage I2 and the recessed projection lfib of the elongated chute 16 respectively as it traverses the tracks and falls down through the said vertical chute l6 and striking the bouncing block lie the large slug B bounds upward against the adjustment screw 22 and is deflected outwardly through the aperture 53 formed by the lower curved edge 20 of the bridging channel I! and the incurved convex portion 30 of the shield 28 and into the slug com partment 41.

A light weight slug C inserted in the slot ll, passes through the angular coin passage II, the sloping track and the elongated chute l6 as hereinbefore described, but after striking the bouncing block l6a of the elongated chute I 6, it may bound through the passage 54 in the bridging channel l8,'pivot the angular arm 3! on the pivot pin 32 and drop down through the slotted chute 24 until it strikes the release gate 44, but having little weight it will move the release gate but slightly and falls over onto and rocks the pivoted beam 31, rolling from the pivoting beam through the passage 55 and into the slug compartment 4'! as shown in Fig; 1 ,andillustrated also in Fi 6.

A proper coin D being inserted in the slot l I, follows the same course through the angular coin passage l2 and the elongated chute 16, but in passing beneath the magnet 18, its fall is checked and the coin D in striking the triangular bouncing block Ilia, bounds upward at an angle and through the passage 54 striking the pivoting arm 3| and dropping down through the slotted channel 24, strikes the pivoted beam 31 and the release gate 44 and pivoting both, drops through into the coin compartment 46.

I claim:

1. In a coin testing device, the combination with a vertical chute, of a spring gate normally projecting under the lower end of said chute at one edge thereof, and adapted to open under the weight of and pass a proper coin but to deflect a light slug, and a rocking beam pivoted below the lower end of said chute at the opposite edge thereof, and adapted to tilt to eject such deflected slug outwardly from the line of the chute.

2. The combination stated in claim 1, the beam being normally horizontal and located below the gate and having its inner end projecting under the normal outlet from the chute.

THEODORE. BIBICOS.
